[ceph-users] cephadm to setup wal/db on nvme

Folks, I have 3 nodes with each having 1x NvME (1TB) and 3x 2.9TB SSD. Trying to build ceph storage using cephadm on Ubuntu 22.04 distro. If I want to use NvME for Journaling (WAL/DB) for my SSD based OSDs then how does cephadm handle it? Trying to find a document where I can tell cephadm to deploy wal/db on nvme so it can speed up write optimization. Do I need to create or cephadm will create each partition for the number of OSD? Help me to understand how it works and is it worth doing?
